Kombu

The kombu is an essential seaweed for the preparation of many sauces and broths in Japanese cuisine. It not only helps reduce the cooking time of grains and legumes, but also pairs well with fish cooked in a casserole or en papillote. It can be found in dried form, as sticks, or as a product to be infused directly in water. This edible seaweed can be used in several different ways. A variety of kombu can be found on the market to incorporate into recipes. Specialising in the sale of Japanese culinary products, Nishikidôri offers in its catalogue a wide range of kombu seaweeds to enhance preparations at home or in restaurants.

FAQ KOMBU

KOMBU SEAWEED

What is kombu?

Kombu is a sea vegetable, known to us as kelp, harvested from the cold waters of Japan, particularly in the regions of Rishiri, Hidaka, and Hokkaido. This brown seaweed is highly prized in Japanese cuisine, where it is a key ingredient in the preparation of dashi. Kombu is rich in umami and iodine, making it indispensable for bringing natural flavours to soups, sauces, and simmered dishes.

At Nishikidōri, the list of available products includes various forms of kombu:

  • wild kombu,
  • dried kombu,
  • kombu powder,
  • crystals (flakes).

Each of them brings a new dimension to cooking. Our seaweed is rich in nutrients and minerals such as calcium, magnesium, and vitamins A and C. Kombu powder, in particular, is very popular among cooking enthusiasts for preparing flavoursome broths.

Whether in powder form, dried leaves, or as an infusion product, the kombu sold at Nishikidōri can be used to intensify the flavours of a variety of preparations. Our customers' reviews confirm the excellence of these products, available directly from our online grocery shop.

The different kombu seaweeds at Nishikidori

At Nishikidori, our varied selection of kombu-based products meets the needs of chefs and cooking enthusiasts alike. Kombu powder, wild kombu or dried kombu seaweed — each variety lends itself to specific uses to enrich dishes with authentic flavours. Here are some of the options available in our catalogue.

Wild kombu

Wild kombu stands out for its superior quality (thicker and more flavourful) compared to farmed seaweed. It retains all its flavours and nutrients. This product features prominently on the list of must-haves for lovers of authentic Japanese cuisine.

Wild Hidaka Kombu seaweed, EXTRA quality

This product is among the must-haves on the list of dried or fresh wild seaweeds. It is ideal for enhancing a variety of culinary preparations. Hidaka Kombu seaweed, originating from Hokkaido, is prized for its gentle dietary fibres and its ability to enrich slow-cooked dishes. It can be used to prepare a dashi with a rich umami flavour, with a darker colour than traditional kombu. The products available, such as this wild kombu, are highly sought after and can be ordered directly from our online grocery store.

Wild kombu seaweed aged in a Kura-gakoi cellar

Coming from the islands of Rebun and Rishiri, in the north of Hokkaido, this new product range is particularly prized for diversifying dietary styles. The wild kombu from these regions is aged for 5 years in controlled cellars, according to the Kura-gakoi method. This process attenuates the pronounced marine flavours and brings out the pure essence of umami. This 5-year-old organic product is rich in iodine. It is perfect for those seeking a seaweed with exceptional flavours. At Nishikidori, wild kombu is available in various forms, including powder, ideal for enriching dishes. This new culinary trend is enjoying growing success among connoisseurs, who appreciate its natural character and versatility. Numerous reviews confirm the high quality of these products from Hokkaido.

Wild Rishiri kombu seaweed

This variety of seaweed (sometimes dried) is most commonly found along the shores of Rishiri Island in Hokkaido. Rishiri seaweed is renowned for its exceptional quality, both in Japan and beyond. To obtain it, the product was first naturally dried and then matured for two full years. This seaweed can be used for cooking vegetables, ramen or fish broths.

Kombu powder

Kombu powder is an ideal product for enhancing dishes with its richness in umami. Sourced from dried kombu seaweed, it comes from wild varieties such as Rishiri or Hidaka kombu, both harvested from the pure waters of Hokkaido. This product brings an intense iodine-rich flavour that enriches broths, dashi, and other culinary preparations. The list of its uses is long, and its popularity is growing among Japanese cuisine enthusiasts. Ideal for those seeking a new taste experience, kombu powder receives very favourable reviews. At Nishikidori, Rausu Kombu powder is one of the most sought-after products among connoisseurs. The seaweed is known for its wide and thin form as well as its very supple fibre. It gives a viscous and sticky texture when soaked in water. It is a product very rich in umami flavour. The powder derived from dried seaweed allows you to create a flavoursome dashi, with a darker brown colour than that of Makombu or Rishiri dashi. This organic product from Nishikidori can be used for Kobumaki (kombu rolls filled with cooked fish) or for Kobujime (raw cured fish). Kombu powder is a key ingredient for enhancing the flavours of many dishes (minced meat, purée, butter, clear broths, dumpling dough, etc.). For those who seek great finesse, we offer ultra-fine Hokkaido Kombu powder. Made from various high-quality Kombu varieties, all sourced from Hokkaido, it is one of the most reliable organic products for enhancing cooking. Orders can be placed directly online on our website. Delivery is made to the address indicated.

Naturally dried kombu

Naturally dried kombu is an exceptional product for great chefs and lovers of Japanese cuisine. Here, the seaweed harvested from the waters of Rishiri or Hokkaido undergoes a natural drying process that preserves all its properties. This process intensifies the concentration of umami for a unique flavour that elevates dishes. This dried kombu is primarily used to prepare dashi, but it can also be rehydrated to enhance soups, stews or salads.

Dried Ma Kombu seaweed for dashi

Dried kombu comes in various forms: as leaves, powder or sticks, making it a versatile product for a wide range of recipes. Thanks to this drying process, it retains its nutritional qualities, in particular its richness in iodine, while also having a long shelf life. Dried Ma Kombu, offered by Nishikidori, is one of the most prized varieties for making clear dashi in Japan. Milder than Rishiri Kombu, it imparts a subtle umami flavour to broths without weighing them down. This very practical product is used by chefs to marinate foie gras in miso, fresh fish fillets and vegetables. Large and thick, dark brown in colour, it also lends itself to making tsukudani. It is ideal for those looking for a kombu that is delicate yet rich in flavour. Reviews are unanimous: dried kombu is an essential ingredient for all those seeking a powerful and rich umami. Naturally dried kombu from Nishikidori stands out for its exceptional quality. It is carefully selected to satisfy chefs and Japanese cuisine enthusiasts.

Dried kombu seaweed julienne-cut

Offered by Nishikidori, this variety is made from Hombaohirama kombu, a wide and long seaweed from the Hokkaido coast. This wild kombu, harvested after a minimum of two years of growth, is dried and then matured for 2 to 3 years. It yields an organic product rich in umami and iodine-tinged flavours. The seaweed, once rehydrated, takes on a tender texture and a refined taste. Very versatile in cooking, this kombu can be enjoyed both hot and cold, as an accompaniment to slow-cooked dishes or in salads. It is easy to prepare. It infuses quickly and retains its greenish colour. This organic product is ideal for enriching dashi broths or even for being fried into crunchy snacks. With its fine strands, it can also pair wonderfully with dishes such as vegetables or fish.

What are the health benefits of Kombu?

If this seaweed is so popular among consumers, it is not solely for its flavour. Kombu is praised for a number of benefits it has on the human body.

Support for thyroid function

One of the best-known attributes of this seaweed is its high iodine content. This mineral is important for the proper functioning of the thyroid. The thyroid plays a key role in regulating metabolism, energy production and maintaining hormonal balance. An iodine deficiency can lead to conditions such as hypothyroidism. Wild kombu, particularly that harvested in Hokkaido, is especially rich in iodine. It offers a natural solution to supplement daily requirements for this nutrient.


Aids digestion

Kombu contains soluble dietary fibre, which helps to improve digestion. Once rehydrated, this fibre forms a gelatinous substance that facilitates intestinal transit. The seaweed also contains enzymes that help break down foods that are difficult to digest, such as legumes. Adding dried kombu when cooking beans helps to reduce bloating and improve digestibility. This process is moreover commonly used in the preparation of slow-cooked dishes in Japan.


A detoxifying effect

Acting as a natural detoxifying agent, kombu contains compounds such as alginic acid, which binds to toxins in the body and helps to eliminate them. In addition to purifying the system, kombu promotes the elimination of waste accumulated in the intestines. Kombu-based products marketed by Nishikidōri allow you to enjoy these properties while incorporating a fresh touch into everyday meals.


Strengthens immune defences

Kombu is also an excellent source of minerals and vitamins. These nutrients help to stimulate the production of white blood cells in order to help the body defend itself against infections. The antioxidants found in kombu protect cells from damage caused by free radicals. By regularly consuming dishes made with kombu, one can naturally improve immunity while at the same time adding an incomparable umami flavour to one's meals.


Contributes to cardiovascular health

Kombu is ideal for reducing cholesterol and protecting the heart. This mineral-rich seaweed helps to regulate blood pressure and prevent cardiovascular disease. By adding kombu to one's diet, particularly in powder form or as dried kombu, it is possible to strengthen heart health while enjoying the nutritious and flavoursome benefits of this ingredient.


Promotes weight management

With a very low calorie intake, kombu is an excellent ally for those looking to lose weight or maintain a stable weight. The dietary fibre found in this organic product provides a lasting feeling of fullness. This reduces appetite and cravings for snacking. Moreover, kombu is a highly nutritious seaweed that provides essential minerals without adding unnecessary calories. Incorporating our dried or powdered kombu into the diet helps to regulate weight gain. For lovers of these food plants, Nishikidōri guarantees a quality product, ready to elevate recipes.


Strengthens bones

Kombu is an excellent source of calcium, an essential mineral for the health of bones and teeth. The magnesium present in the seaweed also aids the absorption of calcium, making it a complete food for maintaining strong bones. By regularly consuming these plants in different forms (dried or powdered), one can prevent bone demineralisation and strengthen bone density.


Stabilises blood sugar levels

Finally, kombu can help regulate blood sugar levels thanks to its soluble fibre content, which slows the absorption of sugars into the bloodstream. This helps to avoid blood sugar spikes. Dried kombu and its various variants, such as Rishiri kombu, are products of choice for those wishing to incorporate healthy ingredients into their diet.


At Nishikidōri, we offer a range of high-quality products, from wild Hokkaido kombu to varieties such as Hidaka or Rishiri kombu. Each of these plants offers unique flavours and an exceptional nutritional value. Orders can be placed directly on our website to benefit from delivery to the specified address.
